The late Richard Hackman of Harvard University once argued, I have no question that when you have a team, the possibility exists that it will generate magic, producing something extraordinary… But don't count on it.

The bulk of the research shows that there may be a pause, or a shifting of gears in the 40s or 50s, but this shift can be exciting, rather than terrifying.

Some people are absorbed in the past but not open to new memories, but that's not the case for me.

Only a few months later Leah opened her first yoga studio, but success was not instant.

Leigh Thompson of Kellogg School of Management in Illinois warns that, Teams are not always the answer—teams may provide insight, creativity and knowledge in a way that a person working independently cannot; but teamwork may also lead to confusion, delay and poor decision-making.

In some ways, you probably go through that process after a big event like your wedding day – but the difference is that thanks to their other psychological tendencies, the HSAM subjects are doing it day in, day out, for the whole of their lives.

I had spent two years cultivating this community, and it had become successful very fast, within six months, but I was facing the prospect of losing it all.

He had always had a good memory, but the thrill of young love seems to have shifted a gear in his mind: from now on, he would start recording his whole life in detail.

But there's an appeal in that vulnerability.

But that wasn't the case.

But is there a point where it reaches capacity?The answer is no, because brains are more sophisticated than that.

But in a new study, researchers demonstrated for the first time how this effect occurs in the brain.

But current studies are beginning to place greater emphasis on the conditions under which we forget, as its importance begins to be more appreciated.

But at least, she says, they can maximize the odds of success.

But a new report by Deloitte, Global Human Capital Trends, based on a survey of more than 7,000 executives in over 130 countries, suggests that the fashion for teamwork has reached a new high.

But I know if you don't grow, you stand still, and that doesn't work for me.

It is not the first time one of Google’s famed self-driving cars has been involved in a crash, but it may be the first time it has caused one.

In the 1600s, people in China used carrots as medicine, but they also ate carrots boiled in soup.

But those surveyed by AAA say they trust their own driving skills.

But people still mostly fed carrots to horses, donkeys and pigs, and didn’t eat them themselves.

But carrots got their biggest boost during the two world wars when food shortages forced people to eat them and governments told everyone how healthy carrots were.

But 75% of drivers say they wouldn’t feel safe in such a vehicle.

Yet I, too, have resisted the idea that food shortages could bring down not only individual governments but also our global civilization.

These patterns suggest that some types of mental flexibility decrease relatively early in adulthood, but that the amount of knowledge one has, and the effectiveness of integrating it with one's abilities, may increase throughout all of adulthood if there are no diseases, Salthouse said in a news release.

Such moves may eliminate the fears of those living in the exporting countries, but they are creating panic in importing countries that must rely on what is then left for export.

Some show up ready, but many do not at this critical time when young brains are developing rapidly.

Obviously there are cultural differences, but if you were talking to another person and they came up close in your personal space, you wouldn't think that's the kind of thing a properly brought-up person would do.

It's no secret that the Mediterranean diet is healthy, but it was also a joy to prepare and eat.

I mean, there are some cautious steps I can take, but ultimately I can not guarantee myself that.

Declining mental function is often seen as a problem of old age, but certain aspects of brain function actually begin their decline in young adulthood, a new study suggests.

But when the researchers plugged in a number of other variables, such differences disappeared.

But what effect does your personality have on your longevity ( ' , 长寿)? Do some kinds of personalities lead to longer lives? A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100.

But water shortages are even more worrying in India.

But unlike the modern definition of Epicureanism as a life of indulgence ( ' , 放纵 ) and luxury, for the ancient Greeks, it meant finding a state of calm, peace and mental ease.

But this and other price shocks were event-driven—drought in the Soviet Union, crop-shrinking heat in the U.S.Corn Belt.

But the new paper suggests that if you want long life, you should strive to be as outgoing as possible.

But that potential pales beside the never-ending demand for crop-based fuels.

But perhaps they don't have to turn themselves into private investigators or Congressional subcommittees.

But nobody greeted the daughter and mother when they arrived, though the visit has been planned; nobody introduced them to the other residents.

Oil prices may rise or fall but economic laws are not subject to change.

It is but a matter of personal taste.

In the past, falling oil prices have given a boost to the world economy, but recent forecasts for global growth have been toned down, even as oil prices sink lower and lower.

I realized these different types of students not only explain their failures differently, but they also hold different theories of intelligence.

Good teaching and research are not exclusive, but they are also not automatic companions.

For instance, talking about mathematical geniuses who were more or less born that way puts students in a fixed mind-set, but descriptions of great mathematicians who fell in love with math and developed amazing skills produce a growth mind-set.

For example, having salt on the outside, but none on the inside, reduces the salt content without changing the taste.

But as the work became more difficult, the students with a growth mind-set showed greater persistence.

But as it turns out, waiters see only a tiny bump in tips when they do an exceptional job compared to a passable one.

But I can tell you that I like this guy.

If you look at a lot of low-income communities in the United States, there are programs that are serving them, but they're primarily centered around ‘Let's get these kids' grades up,' and not around ‘Let's get these kids access to the same kinds of opportunities as more-affluent kids,' said Daniel Zaharopol, the founder and executive director of the program.

Direct subsidies to research and development have been adopted by some governments but are a poor substitute for a carbon price: they do only part of the job, leaving in place market incentives to over-use fossil fuels and thereby add to the stock of atmospheric greenhouse gases without regard to the collateral ( ' , 附带的) costs.

Children grow up learning the skills to succeed in their socioeconomic stratum（ 阶层） but not necessarily others.

But will such contests, which are overwhelmingly dominated by Asian and white students from middle-class and affluent families become any more diverse? Many social and cultural factors play roles in determining which promising students get on the path toward international math recognition.

But there are initiatives in place to try to get more underrepresented students involved in accelerated math.

But the barriers are disappearing, in part because journals and funding agencies worldwide are encouraging scientists to make their data public.

But that's not the only uncertainty.

But renewable energy will have to displace fossil fuels to a much greater extent in the future to avoid unacceptable climate risks.

But efforts are in place to expose more black, Hispanic, and low-income students to advanced math, in the hope that the demographic pool of high-level contenders will eventually begin to shift and become less exclusive.

It concerns not only us sociologists, but also economists, politicians and business people.

We, of course, need to pay attention to youngsters who are filled with discontent and hostility, but we should not allow these extreme cases to distort our view of most young people.

They seem to be turning inward—generally in a pro-social manner, certainly with positive benefits for intimate relationships, but too often at the expense of a connection with the present and future world beyond, including the society they will one day inherit.

There's work to be done, but workers aren't ready to do it—they're in the wrong places, or they have the wrong skills.

The average Norwegian is better off than the average US citizen, but contributes about half as much to climate change.

The Millennium Ecosystem Assessment, a vast four-year global study which reported its initial conclusions earlier this year, found reasons to believe that managing ecosystems sustainably—working with nature rather than against it—might be less profitable in the short term, but certainly brings long-term rewards.

That statement comes not, as you might imagine, from a stereotypical tree-hugging, save-the-world greenie ( ' , 环保主义者), but from Gordon Brown, a politician with a reputation for rigour, thoroughness and above all, caution.

Teaching is so important that it should be like other professions, with high pay and good working conditions but few job protections for bottom performers.

Saying that there're no easy answers sounds wise, but it's actually foolish: our unemployment crisis could be cured very quickly if we had the intellectual clarity and political will to act.

It's true that the main reason inner-city schools do poorly isn't teachers' unions, but poverty.

It's not just about education, but about poverty and justice.

In other words, poor and rich both over-exploit the natural world, but for different reasons.

If our economies are to flourish, if global poverty is to be eliminated and if the well-being of the world's people enhanced—not just in this generation but in succeeding generations—we must make sure we take care of the natural environment and resources on which our economic activity depends.

Clickthrough rates have been high so far ( ' , around 3-4%, compared with less than 0.3% online), but that may be a result of the novelty.

But there are also many examples of growing wealth by trashing the environment, in rich and poor parts of the world alike, whether through unregulated mineral extraction, drastic water use for agriculture, slash-and-burn farming, or fossil-fuel-guzzling ( ' , 大量消耗) transport.

But the data is exact enough for a clear trend to be easily discernible.

But researchers are improving systems to measure a teacher's performance throughout the year, and, with three years of data, it's usually possible to tell which teachers are failing.

But overall, we suspect that spending would come down through elimination of a lot of unnecessary or even dangerous tests and treatments.

But now, as then, powerful forces are ideologically opposed to the whole idea of government action on a sufficient scale to jump-start the economy.

But missing from all these data is the sense that today's young care very much about their country, about the broader civic and political environment, or about the future of their society.

But is this right? Do things get better or worse as we get richer? Here the Stockholm declaration is ambiguous.

But frequently untreated human waste harvested from lavatories is delivered to farms and spread as fertilizer.

But finding hard evidence to support the thesis is not so easy.

But don't bother asking for evidence that justifies this bleak view.

But could Norway keep its standard of living and yet cut its emissions to Moroccan or even Ethiopian levels? That question, repeated across a dozen environmental issues and across our diverse planet, is what will ultimately determine whether the human race is living beyond its ecological means as it pursues economic revival.

But as the working classes prospered and the servant shortage set in, housekeeping became a matter of interest to the educated classes.

But Pay Drechsel, an environmental scientist, argues that the social and economic benefits of using untreated human waste to grow food outweigh the health risks.

But DirecTV, Comcast and Time Warner Cable have all invested in it.

You know, one of the first things I like to tell people when they ask me about the supplements, is that a lot of them are promoted as a cure for your memory, but your memory doesn’t need a cure.

We need more funding and more effort to return these languages to everyday use, says Fred Nowuski of the National Museum of the American Indian, We are making progress but money needs to be spent on revitalising languages, not just documenting them.

But the president may be giving the financial sector too much credit.

But now Israeli researchers are reporting that even sleeping in the same room can have negative consequences: not for the child,but for the mother.

What happens to the centralized electric grid, which took decades and billions of dollars to build, as more and more people become prosumers, who produce and consume their own energy on-site?No one knows which – if any – battery technology will ultimately dominate, but one thing remains clear: The future of energy is in how we store it.

We've held on to this workday structure – but thanks to our digital devices, many employees never really clock out.

This might not be right, but school-leavers who fail to acknowledge as much risk making the wrong decision about going to university.

The wireless age is expanding to include not just our phones, tablets, and laptops, but also our cars, homes, and even whole communities.

The problem isn't the technology itself, but that the technology is being used to create more flexibility for the employer rather than the employee.

The government has moved reluctantly into a sensible public health policy, but with such obvious over- cautiousness that any political credit due belongs to the opposition.

The goal of keeping global temperature rise well below 2 ℃ is commendable but the emissions-reduction pledges submitted by countries leading up to the Paris talks are very unlikely to deliver on this.

The researchers also acknowledged that there are a few areas where race as a construct might still be useful in scientific research: as a political and social, but not biological, variable.

Schoololeavers may moan, but they have little choice but to embrace university and the student debt that comes with it.

Michael Yudell, a professor of public health at Drexel University in Philadelphia, said that modern genetics research is operating in a paradox: on the one hand, race is understood to be a useful tool to illuminate human genetic diversity, but on the other hand, race is also understood to be a poorly defined marker of that diversity.

It's not only unsustainable for workers, but also for the companies that employ them.

In-office wellness programs may help reduce stress levels, but they are hardly an ultimate solution to the problem.

Companies are pushing it hard but make it almost overwhelming even to dip a toe in the water for the average consumer, because there are so many compatibility issues to think about.

Chinese officials say the expansion in Antarctica prioritises scientific research, but they also acknowledge that concerns about resource security influence their moves.

But this third group was not only unexpected, it was so distinct and so large—nearly one third of our sample—that it became a key finding of the study.

But the study warns that it is teenagers who engage in all three of these practices in the extreme who are truly in jeopardy.

But the plan was suspended in July 2013.

But the invisible group wasn't far behind the high-risk set, with more than 13% of them exhibiting depression.

But that isn't why the government—under pressure from cancer charities, health workers and the Labour party—has agreed to legislate for standardised packaging.

But strength of will is the missing ingredient where Mr.

But over the last couple of years, and in this one in particular, we are starting to see companies shift from what is the largest screen size, the smallest form factor or the shiniest object and more into what all of these devices do that is practical in a consumer's life.

But now these segments are looking at slower growth curves – or shrinking markets in some cases – as consumers are not as eager to spend money on new gadgets.

But even when employees are given paid time off, workplace norms and expectations that pressure them to overwork often prevent them from taking it.

But an array of countries are rushing to assert greater influence here, with an eye not just towards the day those protective treaties expire, but also for the strategic and commercial opportunities that already exist.

But a new study finds that there's another group of adolescents who are in nearly as much danger of experiencing the same psychiatric symptoms: teens who use tons of media, don't get enough sleep and have a sedentary ( ' , 不爱活动的 ) lifestyle.

Brazil opened a research station in 1984, but it was largely destroyed by a fire that killed two members of the navy in 2012, the same year that a diesel-laden Brazilian barge sank near the base.

Annual fees have risen from ￡1,000 to ￡9,000 in the last decade, but contact time at university has barely risen at all.

People who live, hunt or fish near bird coloniesneed to be careful, the researchers say, The birds don’t mean to cause harm, but the chemicals they carry can cause major problems.

I’m going to define what love is, but then most of the experiments I’m going to talk about are really focused more on attraction than love.

It’s no surprise that high-profile athletes can influence children’s eating behaviors, but the scientists were able to quantify how prevalent these endorsements are in the children’s environment.

I looked through my suitcase but couldn’t find anything to wear.

But those two beverages aren’t the same.

But by 2014, the death rate from Alzheimer’s Disease for this age group have more than doubled, increasing from 3.8% to 8.5%, making the progressive brain disease the second leading cause of death for centenarians.

But because this population is getting larger, the number of deaths in this group is also increasing.

And I’m going to pick a definition from a former colleague, Robert Sternberg, who is now the dean at Tufts University, but was here on our faculty at Yale for nearly 30 years.

There should be forces in society who should be concerned about the budget, but they shouldn't be functioning simultaneously as doctors, said Dr.

The shift, little noticed outside the medical establishment but already controversial inside it, suggests that doctors are starting to redefine their roles, from being concerned exclusively about individual patients to exerting influence on how healthcare dollars are spent.
